CVE-2022-22235 Information

Description

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated network-based attacker to cause Denial of Service (DoS). A PFE crash will happen when a GPRS Tunnel Protocol (GTP) packet is received with a malformed field in the IP header of GTP encapsulated General Packet Radio Services (GPRS) traffic. The packet needs to match existing state which is outside the attackers control so the issue cannot be directly exploited. The issue will only be observed when endpoint address validation is enabled. This issue affects Juniper Networks Junos OS on SRX Series: 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R1-S2 21.4R2; 22.1 versions prior to 22.1R1-S1 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.2R1.
